Diatomite insulating brick is largely used in the tunnel kilns and
various furnaces where the thermal insulation is needed. Diatomite
insulating brick can be formed by extrude machine and then cut into
pieces by steel wire. Diatomite insulating brick can also shaped by
plastic method. It can be cut into the exact size you need after it
fired.
The clay need to be added into the raw material in order to get
enough strength. In order to improve the insulation properties of
diatomaceous insulation brick, combustible ingredients are mixed
in, such as asbestos fibers, sawdust and etc. After drying, the
diatomite insulation brick is fired in the temperature between **0
to ***0 C.
